The Requirements Checklist to Get Spinraza (nusinersen) Covered by Aetna (CVS Health) in California

Answer Box: Your Path to Spinraza Coverage

Spinraza (nusinersen) is covered by Aetna CVS Health in California, but requires strict prior authorization with genetic confirmation of 5q SMA, specialist oversight, and baseline motor function testing. The fastest path to approval: (1) Gather genetic test results confirming SMN1 mutations, (2) Complete baseline motor assessment using HINE-2, HFMSE, or CHOP-INTEND scales, (3) Have your neurologist submit the prior authorization with all documentation through Aetna's provider portal. If denied, California's Independent Medical Review (IMR) has a 50-61% success rate for specialty drug appeals. Start today by requesting your genetic test results and scheduling your baseline assessment.

Your Documentation Packet

Core Documents Required

  • Letter of Medical Necessity from neurologist
  • Genetic test results confirming 5q SMA
  • Baseline motor function assessment with standardized scales
  • Complete medical history including SMA progression

Letter of Medical Necessity Components

Your neurologist's letter must include:

From our advocates: "We've seen the strongest approvals when families work closely with their neurologist to gather genetic test results and complete baseline assessments before submitting. Taking time to organize all documentation upfront often prevents the back-and-forth that delays treatment access."
